HANDLE-SOCKET FOR DIPPERS.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed October 14:, 1908. Serial No. 457,620.

To all whom it may concern:

Be it known that I, GEORGE W. KNAPP, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Handle-Sockets for Dippers, of which thefollowing is a specification.

This invention relates to a sheet-metal handle-socket for dippers.

Sockets for the wood-handles attached to sheet-metal vessels haveheretofore been made from a flat blank by bending the blank into atubular form and uniting the edges by a longitudinal seam; sockets ofthis character have the merit of being produced cheaply. In sockets thusmade the wood handlehas been prevented from disengagement by one or morepins or screws through the wall of the socket, but this is anunsatisfactory means for confining the handle because when the end ofthe wood handle that is within the socket shrinks, the handle at oncebecomes loose and shackly. It is also well-known that seamlesssheet-metal sockets have been made and that screw-threads have beenformed in such sockets to confine the wood handle. While the handle maybe kept tight in this kind of a socket, the socket itself is tooexpensive to manufacture for low-priced goods.

One object therefore of the present invention is to produce a cheapmetal socket in which a wood handle may be confined and always kepttight.

Another object is to provide an improved construction of handle-socketmade from a flat sheet-metal blank that is coiled-the coil being unitedby a longitudinal lock-seam, and having in that side only of the socketwhich is diametrically opposite the lock seam a short diagonalindentation.

The invention is illustrated in the accompanying drawing wherein Figure1 is a perspective view of a dipper having the improved socket. Fig. 2shows the socket in section and the end of the wood-handle in thesocket. Fig. 3 shows a broken portion of the dipper bowl and the socketattached.

The bowl, 1, may be of any shape and made in any manner; the handle, 2,is designed to be made of wood and the end of the handle adjacent thebowl is slightly tapered and has a screw-thread, 3, that may be formedby any means.

The improved socket, l, which is the subject of the present invention ismade from a sheet-metal blank (not shown). The socket slightly tapersand is coiled around and the coil is united by a longitudinal loclcseam,5. The smaller end of the socket has two ears, 6, bent laterally andadapted to fit against the outside of the bowl, 1, to which they areattached by rivets; these secure the socket firmly to the bowl.

One end of the wood handle fits snugly in the tapered socket, and it isdesirable to avoid the use of pins or screws through the wall of thesocket to prevent the handle disengaging because wood handles fastenedby pins soon become loose. At that side of the socket which isdiametrically opposite the lock-seam, 5, is an indented portion, 7, of ascrew-thread; this indentation extends diagonal with respect to the axisof the socket and for a distance of only about one fourth of thecircumference. It will be seen that it is not practical to form ascrewthread all around the wall of the socket on account of thelongitudinal seam.

The indentation, 7, forms an inward proj ection at the interior of thesocket, and this inward projection presses into the wood at thescrew-thread part, 3, when the handle is turned. The taper of the end ofthe woodhandle, and the short diagonal indentation, 7 in the socket,will enable the handle to be kept tight even when the wood shrinks.

Having thus described my invention what I claim and desire to secure byLetters Patent is,

1. A dipper socket consisting of sheetmetal coiled and having alongitudinal seam and provided at the side opposite the seam with ashort diagonal indentation.

2. A dipper bowl having a metal socket provided with a longitudinallock-seam, and

having at that side only which is diametric-' ally opposite the saidseam an indentation, 7, and a wood handle having its end tapered andscrew threaded and attached to said socket.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE W. KNAPP.
